This invention relates to an improvement in dou-gh moldersof [the type wherein-a curlF roller -is utilized for fabricating :Cylindri- V dough in the :tor-rn `ofsheets. I Yi An vobject of theinvention is to provide Vradjfustable curling or rolling means' which Awill operate eiiiectively Aon sheets :of dough of :various weights and sizes. l

Another obj ect is to provide7 inconj unction Vwithqthe curling or rolling mean-s, anindr Gatorvfor insuring accurate :adi-ustmento the device when it is desired to alter the weight vor `size of the fabricated loaf. Y.

These andfother objects are attained ,by the means; described herein and disclosed in the ,accompanying drawings, .in which i Fig. l is a cross-sectional viewof a Iportion loi ;a dough vmolding device fembodying'the device of invention.

Reference is made to the .co-pending application of WilliamG. Kirchhorgserai Number 115086,

wherein isdisc'losed one type of 'dough Inolderl 'to which the device of. the present invention maybe conveniently attached. i

, ln the drawings, vthe pairs of cooperati'n driven rollers and '7. and 8 and9 correspon 'to pairs of driven rollers-62 and, andv 64 and 65, resp ectli'vely'i of the referred to `application.y Measured lumps of dough are' successivelyinserted between the pair of roll'sSf and 9 where they are ilattened and worked into sheet form. 'The dough yin thisforrn passes vbetween the second pair ofrrollersf andv 7 wherein the flattening operation is completed. s

The .sheet .of-dough thus formed .is projected downward-ly until its vfree end ll strikes the serrated :curling roller l0, which is-dniven in vcounterclockwise direction as indicated .by

the arrows in Figs. 2 and 4. 'The rotating `curling :rolle-r thereupon 'carries the lend 1l toward .a pilot roller 12, driven in Ya countercloclrwise direction 'as indicated 'bythe arrow 13. The pilot roller lthereupon ceniza-ots the end lil Iand turns said endlupon itself. yContinu-ed rotation of the-curling and pilot rollers results in a spiral winding of the sheet-.about @central longitudinal axis `of rotation yllhe roll lor loa'fthus formed is indicated `by 110 Attention is now called to jthejffactithat,

yalthough'the center of gravity 'or .the cylinv krdricalloa- T110 may be disposed considerably .to the right for a lvertical line 14;." passing tlfrrough'tlre central axis or curling roller l0, the counter-clockwise rotation ofthe curling roller will' yserve to preclude gravitation' of theloaf down the face of ythe curling roller. liowever, when a guide l (Figa) isii'iter'-A posed between loaf 110 and curling roller l0,-1

Aas 'shownythe lifting action .of the curling roller is immediately overcome Vwhereupon loa-f l1()v will roll Ydown the outer face 16 of guide l5 under the influence of gravity. `It should be noted that the size andweightof loai` will bear al direct relationship to ythe dista-rincer end 17 of the guide -froinimaginary llinelllg For example,iiinoperation,

the guide l5 (Fig. i) were moved in/a'clockwise direction seas to increase .thedistance frornline 14 to Yend l?, the liftingf'orce o'f lcurling roller 10 on the leaf may. eXceedthe downward force of gravity,V whereupon 'the loaf wouldI be rotated indefinitely on .top of the. curling roller. li, however, the guide l5 bemovedi-n the opposite direction,'towardv line 14, .the lifting `force of the curlingroller 'is overcome, whereupon the force of gravity, aided byrotatingpilot rollerlQ, causes displacement of the loaf. f

lThe ineansfor accomplishingthe aboveis Y f as iol-lows The dough molderirarne- 'l8comprises a pair or upright sides l9and 20 vprovided with suitable bearings for vrotatably supporting the rollers 6 7,` Sand Y9. A;

shown in Fig. 2, slidable bearings 21,.actuable` by handwheels 22 and screws 23, may be employed for adjusting the distance of roller 7 from roller 6, and roller 9 from roller S. By the above adjustingmeans, masses of dough passing through the rollers may be fabricated into sheets of various sizes and thicknesses.

The pilot roller 12 is suitably mounted ona shaft 24 rotatably mounted at 25 in the uprights ofthe frame. Each upright ,is pro-n vided with an extending boss 26 having a bore 27 Vin which is rotatably received a-shaftv28 upon which the curling roller is mounted.

Shaft 28 may be driven by any suitable-V j the disks, the disks will of course move in unison. It will be noted therefore that guide may be moved from the position shown inFig.-2, to the position shown inFig. 4, by simply imparting slight rot-atory motion to one ofthe disksfsuch as 30.V Movement of `the' guide in the abover manner serves to ac` complish gravitation of the roll or ashereinbefore described. j VThe means for imparting partial rotation -to disk `30 comprises a longitudinal rod 35 having pivotal mounting on disk30 by means of aiperforate lug 36 on thelower end of rod 535, which receives a stud 37 carried by disk 30.V #As shown in Fig. 2, rod may, if desired, be made in two parts 38 and 39 suitably connected by means of apivotal pin 40. Said connection provides for flexibility and easy Amanipulation of the guide mechanism. The upper portion '33 of rod 35 is suitably supported in a bracket 41 mounted on the upright loaf 110 Y 20. Bracket `41` is provided with an en-` larged bore 42 `which slidably receives rod j 38.V v Rod 38 is suitably threaded at its free end 43 for .receiving a hand wheel 44 provided with co-operating internal threads 45. It will be understood that by manipulating the hand wheel 44, rod 35 may be reciprocated for imparting rotatory motion tothe disks Vand guide 15. A' collar 46 maybe secured on rod 35 by any suitable means'such as a set lfor indicating the position of the guideV 15 relative to theloaves of dough 110.

Although `the drawings show, a curling Guide 15 is curved so as to con'-l roller `of a particular type, is to be understood that a curling roller of any other construction will co-operate satisfactorily with guide 15. It is to be noted also that various means of assembling the dough molder will Y permit of using a one-piece disk 30.

From the foregoing it should be clcar'that a roll or loafof dough 110, after being formed upon the top of curling roller 10 maybe read- `ily vdisplaced from its position by advancing the guide 15 beneath the loaf. Said'adva'ncement of the guidey serves to lift the loaf out of contact with the 4curling roller,therebyv overcoming the lifting force of the curling roller, and allowing gravity to act upon the cylindrical loaf. This operation has been described in detail ina preceding paragraph.

Means isrprovidedfor directing 'the cylin drical loaf from the curling roller onto the- Y revolving drum of the dough molder.

`Said means comprises a pair of spaced adjustable guides 51 mounted in an upright position upon. a transverse bar 52 suitably/ secured to the sides 19 and 20 of the dough molderzframe. ln the drawings, said bar 52 is shown supported by a pair of brackets 53 mounted upon the upright sides of the dough molder. Each guide 51 comprises an upright flat portion 54 which provides -an abut'- c be directed onto the `rolling surface 59 of revolving drum 50. A. pressure board `60 cooperates with said drum 50 for elongating thecylindrical roll of dough directed thereonto bythe guidesf51. VAnnularflanges 61 of the drum limitthe extent to which therolls of dough may be elongated.

lt should be clear from the foregoing eX- planation that a sheet of dough rolled into the shape of a cylinder may be readily discharged from the curlingV roller byV placing the curler guide 15 in adjusted position. TheV cylini120,

drical rollupon being discharged from the curlingV roll, is directed onto the drum 50 by guides 51, whereupon it is further shaped and formed by the druni'and co-operative pressure .board in theusual manner.

It is toy be understoodthat various modifi- Y cations may be made inthe structural details of the Vdevice without departing from the spirit and scope of this invention as set forth Ain the appended claims., f
